Qin Kai touched the stone and said, "Gu Yancheng, this is what I prepared for you." Gu Yancheng knew Chongyi's ability very well, and the army also paid a lot of money to ask him to decrypt and save people. The world's evaluation of him is: there is no code that he can't decipher, but no one can decipher his code. And I heard that he has been living in seclusion for many years, and I don't know if he is still alive.

Gu Yancheng suddenly pulled out a gun and pointed it at Qin Kai's head, "I shouldn't have let you go before." "Thank you for letting me go, I can finally avenge my sister. Do you understand now that you can't save yourself and can only wait for your loved ones to leave? You have lived a privileged life since you were a child, you are smart and capable in the army, do you remember the eyes of your sister who admired you? Why don't you go and save her first? Let her die in the fire. I have been dependent on her since I was a child, and I only have her in my world. ”

"Don't you know she's a spy? It's that you're too obsessed. You can let me die and spare my family. Gu Yancheng put down his gun. Qin Kai pressed the Teng-shaped button on the stone, which was an exclusive seal designed by Chong Li.

"Don't say I won't give you a chance, solve this is the code on the wall, and maybe see them for the last time." After speaking, Qin Kai fell.

Qi Junyi walked over and probed Qin Kai's breath, "The poison that he bit the bottom of his tongue is already dead." "At this time, Gu Yancheng's heart is like ashes, but he must be calm, as long as there is the slightest opportunity, he can't give up." The third child, send people to find Chong Yan without doing everything. Fourth, send a team of people outside to find out if there is any other exit, and dig a tunnel for me. Gu Yancheng shouted, and then began to solve the password of the stone wall.

Qi Junyi and Lu Anfeng went out to explain everything, "This Qin Kai is really a madman, I didn't expect to see Gu Lao and them in the morning, and it was the last time." It hasn't appeared for so many years, how can it be possible to find Chongyi, let alone crack Chongyi's code. Lu Anfeng said to Qi Junyi.

"Don't let the city hear this, didn't Qin Kai just say that if he broke the password of the stone wall, he would still be able to see Gu Lao and them. Let's go back to helping the city. Qi Junyi said.

"Boss, it's all explained!" Lu Anfeng Road. Gu Yancheng was still cracking the code of the stone wall, and Qi Junyi and Lu Anfeng were also analyzing.

"Grandma, wake up." "Mom..."Bei Xin and the Gu couple are waiting for Gu Lao to wake up." Where, what's going on? Gu Lao opened his eyes, and Bei Xin helped Gu Lao up. Gu Xinbo told them about the approximate situation, and Gu Lao was also frightened.

All electronics were removed before they were brought in, but presumably more than half a day had passed, and they couldn't wait any longer. "Mom, you and Grandma are here first. My dad and I looked around. Behin suggested.

It was already ten o'clock in the evening, and Gu Yancheng and the others were still solving the stone wall, and the lunch box placed next to them had not been touched. But at this time, Gu Yancheng had already found the pattern and was making the final crack. "City, cracked!" Lu Anfeng saw hope and cried out.

An invisible screen appeared on the stone wall: Sure enough, it's Gu Yancheng, and even Chongyi's code can't stump you. It's a pity that behind this stone wall is a three-layer increase in Chongyi, I wonder if your father can solve it like you? I'm going to let you see how your family leaves you one by one. My sister and I can rest easy. Hahahaha...

"This Qin Kai is too terrifying, and Yan Cheng has to look at Gu Lao and them inside..."Lu Angfeng said, "Boss, let's go out, let's think of a way." Gu Yancheng pushed Lu Anfeng's hand away, "I still want to see grandma and parents." The stone wall screen cuts to the Vault.

Gu Yancheng could see Gu Lao leaning weakly on Gu's mother, and Gu Xinbo and Bei Xin walking around. Gu Yancheng knelt down against the stone wall, "I'm sorry, I'm sorry." It's my conceit, I think I can control the situation, so I let you suffer, I'm sorry..."

"Cheng, don't look at it, okay. Let's go out and figure it out. Qi Junyi pulled Gu Yancheng up, they didn't want Gu Yancheng to keep watching Gu Lao and them leave, because it was too cruel.

"I'm not leaving, I'm going to leave with them." Gu Yancheng said. "Cheng, Gu Lao, they will want you to live." Lu Anfeng said. "If you were me, would you?" The two didn't say anything more, and they also sat beside Gu Yancheng to accompany them, because they knew that they were the only ones left by Gu Yancheng's side.

In fact, the hole is also very small, there is nothing to eat, "I have knocked everywhere is solid, this should be a confined space." Gu Xinbo said. But how do we get in when it's closed? Gu's mother asked. This is supposed to get us in and seal the only exit. Gu Xinbo responded.

Bei Xin was still looking around, and Old Madam Gu was about to say something, but Gu's mother helped Old Madam Gu up. "Mom, what do you see?" Gu Xinbo asked nervously. Gu Lao slowly spoke, "When people are old, they can't escape a catastrophe. It's just that I'm suffering from you, and I'm worried that we won't be able to live without Yancheng. It made this child even more miserable. "Hold Bei Hsin's hand as he speaks." Yancheng is for the sake of the army and the country, we are implicated as his family, I have no complaints, I am proud of Yancheng for the death of loyalty. But Xin'er, it was grandma who hurt you. Grandma knows that you don't love Yancheng, it was grandma who deliberately matched you to get together, you are still so young..."

Gu Yancheng looked at and cried when he listened to his grandmother's words. Bei Xin hugged Gu Lao, "Grandma, no matter what happened before, I got married to Gu Yancheng, and you are my family." Believe in Yancheng, he will save us out, he's so powerful, isn't he? Gu Yancheng outside the stone wall, "I'm sorry, I'm sorry..."

"Grandma, don't cry! If you cry again, you'll be deprived of oxygen. Bei Xin helped Gu Lao wipe his tears. Suddenly, Beshin turned to look at the oil lamps around her. "Dad, you see we've been in for so long and we're still breathing so smoothly, and the oil lamp is still on. It means that there is an exit here, otherwise the lights will not be lit. Shall we take a look around? ”

Gu Xinbo and Bei Xin looked closely at the surrounding walls again, and Bei Xin found a black dot in one of the corners. "Dad, come over and see what this is." Bei Xin's appearance filled the whole picture, and Gu Yancheng only now found that it was the first time he looked at her carefully, recalling everything that had happened to her.

Gu Xinbo, who also spent time in the army when he was young, saw at a glance that it was a military camera, "This shows that Gu Yancheng is very likely to be watching, and it also shows that this point is a very important place, so he will put the camera here." Bessin spoke her guess.

"Yancheng, you must live! Either way, we want you to stay strong. Gu Xinbo said to the camera. Outside the stone wall, Qi Junyi put his arm on Gu Yancheng's shoulder, "City, live!" ”
